DEPT                           DEPT COMPUTING AND DATA PROCESSING
SUB    DECOMPRESSION           DATE 30 APRIL 1990

     HAVE I MISSED SOMETHING?
     DURING THIS DISCUSSION I HAVEN'T NOTICED ANY COMMENT ON
     GASSES TRAPED IN THE INTESTINAL TRACT. DURING MY US AIR
     FARCE DAYS I WAS ON FLYING STATUS AND WAS REQUIRED TO TAKE
     THE PHYSIOLOGICAL (ALTITUDE CHAMBER) TRAINING. ONE OF
     THE DEMOS WAS DECOMPRESSION. THE CHAMBER WAS TAKEN FROM
     8,000 FEET TO 30,000 FEET IN A MATTER OF SECONDS. OUR
     TASK WAS TO GET AN OXYGEN MASK ON, SURVIVE AND MAKE
     SURE THAT THE PERSON NEXT TO US HAD DONE THE SAME.

     THERE TWO VIVID MEMORIES FROM THIS EXPERIENCE

     1.  THE CONDENSION OF WATER IN THE AIR MADE A THICK FOG
         AND FINDING THE OXYGEN MASK DIFFICULT.

     2.  THE GAS IN PEOPLES INTESTINES EXPANDED 7 TIMES
         WITH RESULTS RANGING FROM MILDLY FUNNY TO AGONY.

    The girl I knew was at ISU. I am at Bradley. There is a
    difference, but never mind. Yes, I know that there are
    graduation standards for high schools. Even the Chicago Public
    High School I went to made us take 3 of science and 3 of
    mathematics. Nevertheless, I personally met the girl, who
    lived in a rather rural area of Illinois, and asked her why
    she was being tutored by my friend, an EE, in what I called
    "jolly numbers"-pre-algebra to the educationalists-and she
    answered, "Because I never took a class in the subject." She
    appeared to be serious. I was sort of shocked.

    The Feds provide some money, as I recall. But the state does
    does provide the bulk of the money. All I know is that
    someone's stiffed the American student, and I, at least, am
    not too happy about that.

    Most do. But what we have here is a case of a self-fulfilling
    prophecy. The average teacher is a liberal-arts type who
    avoided science like the plague (my mother was a teacher.
    She thought microwaves made aluminum angry.). This teacher
    is taught on how to teach-not on a subject, just how to teach.
    He/She is happy until they are hired, and told to teach,
    horrors of horrors (;-)), SCIENCE. So, the teacher tells the
    students that this stuff is hard, and that they are expected
    to have difficulties. Students are scared off by it, except
    those who are stubborn enough to say that they *will* tough it
    out, or those who are in the fortunate minority who enjoy the
    class, and later become scientists or engineers.

    Also, remember, a lot of people forget their science learned
    in high school. Most people can't even do simple physics, let
    alone chem or astronomy.

Do recall that violation of conservation of momentum implies violation
of conservation of energy in another reference frame.  So you could
power a putative "inertialess drive" with a perpetual motion machine of
the first kind.

   Well, that statement would be exactly right if there were no known
stars which supported life-bearing planets, but the presence of at least
one life-bearing planet (ours) enables us to do some rudimentary
probability analysis. You are right in your last sentence, and I don't
dispute the point that the sheer number of stars cannot assure the
existence of life elsewhere. I personally believe it is very likely that
there is life elsewhere, mainly because of the analysis I presented,
along with the argument that it would be quite a coincidence if 'r' were
even within an order of magnitude of '1/N'.
   My point was merely this: if somebody came up to you tomorrow with a
machine would would, by some unknown means, count all the stars with
life-bearing planets in the universe, and before turning it on he bet
you N dollars that there would be none other than ours, you would be
well advised to take the bet at up to odds of 1.7 against you (you put
up $1.70 to win $1.00). This is from (1-1/e)/(1/e) = 1.72.
   Obviously my analysis says nothing about the actual number of stars
in the universe which support life, but _it_does_say_ that it is _more_
_likely_than_not_ that there is other life out there.

    I had been taught that (and read this in Patrick Moore's THE
    AMATEUR ASTRONOMER) any planet inside the Earth's orbit, and
    including the Earth, was an inner planet. Asimov's various
    scientific writings back me up here too.

>Or am I wrong and Australian science education is lacking as well?

    Nobody teaches anyone astronomy these days. It's submerged in
    "general science" or "earth science" courses for the dim high
    school student, upon whom it is completely lost. I have
    *never* heard of a single physics class that taught anyone
    astronomy in high school, at least in the U.S.A., where the
    "traditional" science curriculum, where it exists, is biology,
    chemistry, and physics. I could, of course, consider the
        "brilliant" ;-) idea of a single course of "physical science"
    replacing both physics and chemistry as the typical curriculum
    now.
